Specicaton of Letters Patent.

Patented Feb. 22, 1910.

4a citizen of .the United States, and residing in the city, county, andState of New York, have invented an Improvement in `lZVrapping-Machines,of which the following isa specification.

y My invention relates to machines for wrapping articlesinpapers orother covers, and has for its primary object the provision the articleto `be wrapped, the paper in which it is wrapped andthe folding,-tucking and laying of the cover about the article.

. Another `object is to secure `a higher lrate of speed in `wrapping thearticles, and the avoidance of defects existing in the prior machines.Other objects will appear hereinafter. My invention consists of featuresof construction, arrangements and :combinations of devices hereinafterdescribed and more particularly pointed out in the appended claims.

My invention is embodied in the mach-ine illustrated inthe accompanyingdrawings, forming part fof this specification, in which-.- Figure 1 is aside elevation of the machine; Fig. 2 is a plan view partly in sectionon the plane B-B of Fig. 1; Fig. `3 is a vertical sectional view of themachine taken inside the side-frame of Fig. 2; Fig. 4 `is a view from`underneath of a part `of the upper folder; Fig. `5 `is a view from aboveand also from the front of the first pair of folders; Fig. 6 embraces aplan and a side view of a cutter and operating mechanism therefor; Fig.7 is a diagrammatic view 4illustrating the beginning of the wrappingoperation; Figs. 8, `9, 10, 11, 12, 13, 14 and 15 are diagrammatic viewsillustrative of the various steps or stages in the process y -ofwrappingan article; and Fig. v16 is a perspective view of the wrapped article.

In the drawing, the reference numeral 11 l marks legs for supporting atable v18 and the reference 30 designates two .uprights or l i`standards bolted or otherwise secured toi the platform` or table 18.Beneath the table 18 and suitably` mounted in bearings connected withthe side frames .or legs 11, is a :main drive-shaft 19 journaled in'bearings 20. A cam 21 issecured to the shaft 19 and is arranged tooperate the plunger 22, which slides ina housing or bearing 63 attachedto the said platform 18 through a `connection between the said cam 21and the said plunger 22 consisting of a lever 23 which is ful- :crumedat 24 and which is connected with the plunger by means of a slot and pinv24". The shaft 19 is also pro-vided with a cam 25 for `operati-ng theplunger 27, the cam 25 operating on a lever 26, which lever is connected:by a slot and a pin 26)c with the slide or plunger 27. The plunger 27moves at right angles to the direction of motion of the plunger 22:aforesaid and in `the same plane on top .of the platform 18.

`The reference 31 `marks a rod or shaft removably mounted in bearings inthe side frames 30; the said rod or shaft 311 forming a bearing for aroll of paper 32. At each side :of the roll 32 and attached to :the rod31 is an arm 33, the said arms extending forward from said shaft to apoint adjacent to the guide roll 41. The said arms are connectedtogether by rods or ties 34, 35, 36 and the outer rod `36 has looselymounted thereon two rolls 38, 39, which coact with the roller or rollers41, to feed the paper forward. As indicated in Fig. 3, the paper passesbeneath the rod 34, over the rod 35 and under the rolls 38, 39 and overthe rolls 41 and down through the throatway 62. The rolls 41 are looselymounted on a shaft 40 which is journaled in the side frames 30aforesaid. The shaft 40 has a Agear wheel 51 and a sprocket wheel orpulley 43 fast thereon, while the shaft 19 aforesaid has acorresponding'sprocket wheel or pulley 28 fast to it, and the saidsprocket wheels or pulley are connected by the sprocket `chain or belt29, whereby the shaft 40 is driven from the shaft 19.

In front of the shaft 40 and roll 41 is a bar 53 for connecting the sideframes 30, and this bar `53 at a point in front of the roll 41 formspart of a throatway or guide 54 through which the paper 32 passes on itsway to the .throatway 62, there being a plate 55 in front` of the bar 53andprovided `'with a backwardlycurved tongue or guide :blade V57 whoselower edge forms a cutter coacting with the knife 58 now to bedescribed.

At one side of the said throatway 54 is suitably journaled a rocking armor bell-lever 45 which has rollers 60, 61 thereon for coaction with acam 44 on the shaft 40. The blade 58 is adjustably secured to an arm ofthe bell-lever 45 and coacts with the cutter 57 to sever the paper intoproper lengths.

The web of paper is intermittently advanced by means of the circularsegments 49, 50 fast on a shaft 46 journaled in bearings attached to theside frames 30 aforesaid.V The shaft 46 isL provided with a gear 52,fast thereon, which meshes with and is driven by the gear 51 aforesaid.The shaft 46 is journaled in bearings 47 which are movable withv respectvto the side frames 30 and which are held there against by the screwbolts and springs 48, thereby giving a yielding pressure between the.segment disks 49, 50 and the roller or rollers 41. rlhe paper isgripped between the rollers 41 and the segment rollers 49, 50 and is fedforward as long as these are in contact with each other and no longer.

The articles a are placed in the guideway 67 which is bent down in frontof the plunger 22 at 64. This guideway is cut away at the front and backto allow the plunger 22 to pass through to push' the article therefrom.The articles in the guideway 67 are fed forward by means of a belt 65running on pulleys 66, the said belt acting on the articles a fromunderneath, as indicated in Fig. 3. The throatway 62 is also cut away toallow the plunger 22 to move the articles through the said throatway 62,but the sides of the throatway 62 are channeled to guide the .wrappingpaper to a point below the platform 18, whereby the article a, as it ispushed from the chute 64, will impinge against the paper at about thecenter thereof as indicated in Fig. 7. The throatway 62 is composed of arear plate 68 and a front plate 69 and these are attached to theplatform 18 by brackets and screws or otherwise. The lower edge of thepaper passes through a slot in the table 18 and is arrested by the V-shaped stop 70 which is held in place by the adjustable screws 71, 72,the function of the stop 70 being to arrest the paper in the properposition for the beginning of the operation of wrapping as the plunger22 moves the article forward. As the plunger 22 moves the articleforward from the position illustrated in Fig. 7, the paper is turneddown to the position thereof shown in Fig. 8, by the top and bottom ofthe slot in the throatway 62, the reference 73 indicating the lower flapand the reference 74 the upper flap of the paper. As the plunger 22continues its motion,`the article is forced between the tucker fingers75, which turn in the middle portions c of what may be termed the endsof thewrapper, to the positions thereof shown in Fig. 9.

Immediately in front of the paper throatway 62 are two plates 76, 77,the upper plate 76 of which is provided with flaring scrolls 78, 79,which, during the advance of the article toward the front of themachine, turn down the ends of thetop flap 74 from the position thereofshown in Fig. 9.to the position thereof shown in Fig. 10. The said plateY7 6 has an extension at right angles to that portion which carries theabove mentioned scrolls and such right angle portion is provided with aspring finger 80', the function of which is to hold the article and itspartially folded wrapper in position while undergoing further wrappingoperations. The said plate 76 has also secured thereto a spring scrollor finger 81. The lower plate 77 has secured thereto scrolls or folders82, 83 which are adjusted Yin rear of the scrolls 78, 79 and act to turnup the ends of the lower flap 73 from the position thereof shown in Fig.10 to the position thereof shown in Fig. 11. The said scroll 82 hasattached thereto a Hat spring 84 vwhich holds the partially foldedwrapper in position at the end of the stroke of the plunger 22 so thatthe article and the wrapper may be operated upon by the secondplunger-27. The scroll 83 has attached thereto a supplemental tucker 85which, as the plunger 27 is operated, acts on the projecting overlappingfolded-in front ends of the flaps 73, 74 (see Fig. 12) and turns them infrom the position thereof indicated in Fig. 12 to the position shown inFig. 13, as said plunger 27 moves the article onward. As the plunger 27comes forward, the tucker 100 which is attached thereto, tucks in theoverlapping ends of the flaps 73, 74 from the position thereof shown inFig. 11 to the position thereof indicated in Fig. 12, corresponding tothe turning-in done by the tucker 85 aforesaid. The plunger 27 isattached to a bar 88 which works in the guideway 87 in front of themachine. The plate 77 has an extension 7 7 X to which is attached ascroll 86. As the plunger 27 continues its advance motion, the scroll 81above described turns down the remainder of the flap 74 from theposition thereof shown in Fig. 13 to that indicated in Fig. 14 andduring the further advance the scroll 86 turns up the last portion ofthe lower flap 73 from the position thereof shown in Fig. 14 to theposition thereof indicated in Fig. 15, thus completing Vthe wrapping ofthe article. The plunger 27 has a motion substantially equal to thelength or width of the article, so that each article ypushes itspredecessor ahead of it andthereby causes the folding operation abovedescribed to take place. The spring 80 retains the articles released bythe plunger 27 the moment the said plunger begins its reverse orreturnmotion.

The machine above described is simple in construction and operation andis small and l t compact.

While the tucker 100 is shown and described asbeing attached to theplunger 27,

are guided down into the chute 64 and are held therein by their endsexcept that the lowest article of all may be pushed from `underneath theremainder by means of the plunger 22 over against the paper as indicatedin Fig. 7 which paper has previously been severed from the roll of webby the n chute or throatway 62. The further adknife 58 and which standsupright in the vance of the plunger 22 toward the front of the machinefolds the paper about the article as indicated in Fig. 6, as said paperpasses through the opening beneath the bottom plate 77 and the backplate 68, and

thereafter the curved ngers or tuclrers 75 fold in the center endsections c of the overhanging flaps 7 3, 74 (see Fig. 9) and thereafterthe scrolls 78, 7 9 fold down the ends of the top iiaps 74 as indicatedin Fig. 10v

after which the scrolls 82, 83 fold up the ends of the flaps 78 asindicated in Fig. 11 and as this operation is completed, the article hasbeen removed to a position directly `in front of the plunger 27, whichthereafter advances and the tucker 100 folds in the doubled-up ortwo-ply ends of the flaps 7 3, 74, as indicated in Fig. 12. The plunger27 advances farther and forces the article by thetucker 85, which tuckerfolds in the two- Vply or doubled ends of flaps 7 3, 74 at the leadingend of the article,'as indicate-d in Fig. 13, after which the scroll 81folds down the upper flap 74 as indicated in Fig. 1 4, leaving whatremains of the iap 73 eX'- tended as shown in Fig. 14, and thereafterthe scroll 86 lifts the iap 73 from the position thereof shown in Fig.14 up against the side of the article as indicated in F ig. 15. It willbe understood that the plunger 27 `does not move the articles the fulldistance required by the operation above described but that the`succeeding articles advance *those ahead and cause certain of theoperations to be performed. The articles wrapped as shown in Fig. 16,are pushed out at the left of the front of the machine (lower side ofFig. 2) into a suitable receptacle.

-The scrolls hereinbefore mentioned are in the nature of helical orwarped surfaces, and have what may be called their leading ends parallelwith the flap to be moved, so that they begin to act upon the flaps 74or 78 at all points of its width and gradually turn the front edge ofthe ap over against the side of the article; this is equally truewhether the scrolls act at the end of the article or at its side.

What I claim as new is 1. In af wrapping machine, the combination ofarticle feeding and wrapper feeding mechanisms, a plunger and foldingdevices for folding the wrapper about the front, top, bottom and ends ofthe articleas said plunger advances it, a second plunger operating atright angles to the first, a tucker attached to said second namedplunger for folding the rear end of the wrapper upon the article andfolding devices to fold in the other end of the wrapper and the flapsthereof to inclose the remaining side of the article.

2. In a wrapping machine the combination of a plunger for advancing thearticle, means for interposing wrappers in the path of the article movedby said plunger, adjustable means for arresting said wrappers in saidpath, folders along the sides of said path for laying the wrapper uponthe fron't, top, bottom and ends of the article, a second plungeroperating at right angles to the first plunger, a tucker carried by saidsecond plunger for folding in the rear ends of said wrapper and foldingdevices in the path of the article as moved by said second plunger forcompleting the` laying of the wrapper about the article.-

3. In a wrapping machine, the combination of two plungers operating atright angles to each, other, folding devices for partially folding thewrapper about said article as the latter is advanced by one plunger, aspring forming a continuation of one of said folding devices for holdingthe wrapper in contact withthe article until the second plunger advancesand a second set of" TI-IEODORE Gr.
